Abstract
A biosensor device is provided, including a first semiconductor layer formed over an interconnect structure. A plurality of detection elements are formed in the first semiconductor layer. An optical filter layer is formed over and physically contacts the first semiconductor layer. A second semiconductor layer is formed over the optical filter layer, having opposing first and second surfaces, wherein the first surface physically contacts the optical filter layer. A plurality of isolation walls are formed over the second semiconductor layer from the second surface thereof, defining a plurality of micro-wells over the second semiconductor layer, wherein the isolation walls and the second semiconductor layer comprises the same material, and the micro-wells are correspondingly arranged with the detection elements. An immobilization layer is formed over the second semiconductor layer exposed by the micro-wells and a plurality of capture molecules are formed over the immobilization layer in the micro-wells.
